COLTER ATTACH M ENT.

SPECIFICATION forming part of Letters Patent No. 231,074, dated August10, 1880. Application filed March 6, 1880. (a. model.)

To all whom it may concern Be it known that I, KINYON W. MANWAR- ING, ofDe Witt, Olinton county, and State of Iowa, have invented a new anduseful Improvement in Plow-Oolter Attachments, of which thefollowing isa specification.

My invention relates to the attachment of the yoke shaft of a plowcolter to a suitable clamping device employed to fix the colter to theplow-beam; and the devices employed, their construction, application,and mode of action will be hereinafter more fully explained.

- In the accompanying drawings, Figure 1 is an isometricalrepresentation of a colter attachment embodying my invention in place ona portion of a plow-beam, and at Fig. 2 is represented a verticalcentral section in the lengthwise direction of the plow-beam.

In the figures, (t represents a portion of a plow-beam, on which, inconnection with a suitable clamping device, my improved attachment ismounted. The clamping-frame in this instance is substantially the sameas the frame patented to me September 30, 1872), No. 220,161; and itconsists of plates b, suitably separated and relatively tixedin suchseparated position by transverse bars 0, d, and e, and are alsoperforated, as at f, to receive screw clampingbolts h, which, inconnection with a clampin g-plate, 1 serve to fix thcclamping-frame inan adjustable manner to the plowbeam.

The outer edges of the transverse bars care corrugated in the lengthwisedirection of the clamping-plates, as shown in the drawings; and theconnecting-bars d are placed to form a transverse slot to receive aclamping-bolt employed to fiX in place thereto in an adjustable manner asuitable socket to receive the shaft of the colter-yoke.

At k is represented a coltereshaft socket fitted with arms 1, havingtheir end portions corrugated to engage the corrugations in thetransverse bars. This colter -shaft socket is provided with a centerarm, m, provided with a center opening to receive a clamping-bolt, n,which is passed into position in the arm through a suitable opening, 0,in the outer surface of the socket, and when in place in the frame, inconnection with a suitable screwnut, serves to hold the socket to theclamping-frame in such a manner that it may be readil adjusted laterallyto properly align the colte ith the plow; and it is capable of avertical inclination laterally to properly adjust the colter with theplow, which is accomplished by inclining either end of the socket to orfrom the plow-beam, or at an angle to the vertical center thereof. Thissocket is provided with a boss, 1), at or near its ends, which are eachfitted with a set-screw, s, which operate against a plate or bar, 8,placed in a key-seat-like groove, 8, formed in the socket immediatelyundertheset-screws. Thissocket receives the journal-shaft t of thecolter-yoke freely in such a manner that it may be adjusted verticallyto regulate the running depth of the colter supported in the yoke, andmay be adjusted on its axis to align the colter to the line of theforward movement of the plow, and when adjusted is firmly held inposition by the clamping force of the set'screws.

At a is represented a colter of the usual fox m, made from the materialusually employed in such work, and is mounted to revolve between theyoke arms in bearings formed in their lower ends, substantially in theusual manner.

By this construction and arrangement I am enabled to produce, at a smallcost, a reliable rigid colter (known as such in the trade) capable ofall the required adjustments to reuder it a practical article of itskind.

I am aware that a tubular socket has been provided with a set-screw forretaining the yoke-shaft in any desired vertical adjustment, and I makeno claim to such construction, as my invention relates to the peculiarconstruction and combination of parts described, and pointed out in theclaim.

I claim as my invention- The combination, with the clamping-frame, acolter-shaft socket provided with continuous tubular bearings at itsupper and lower ends, and a fastening-bolt which is inserted through anopening in the socket, the head of the bolt being seated in a recessformed on the inner surface of said socket, of a clampingplate insertedbetween the colter-shaft and socket, and clamping set-screws inserted inthe socket and adapted to secure the coltershaft in any desired verticaladjustment, substantially as set forth.
